I can start today.
I'm a specialist animator focusing on the areas of logo, intro, and brand animation.
What you describe is a semi simple process for a professional.
The cactus can use a system called hair particles to build the spines, and the aflame fiesta below can be completed relatively painlessly using volumetric effects.
I can complete both of these quickly and accurately with your revisions.
You'll note that my portfolio has some similar styles of work and a large body of my specialty animations. Please also see my reviews for an idea of my work ethic and style, as well as professionalism.
I'd love to hammer out the details and get a jump start on this for you, so please do initiate a chat so we can discuss the finer points and get going with the animation!
Looking forward to your response!
Best Regards,
Jacob Dodd
